Hi, In STON #bleedingEdge I added the ability to write and read Class and Metaclass instances by using their global name. So, Point will be written as Class[#Point] while Point class will be written as Metaclass[#Point]. This is of course a short-circuit solution for the complex structure that a class actually is, but a reasonable compromise. It is in any case better than not handling these types of instances, which was the case before. === Name: STON-Core-SvenVanCaekenberghe.64 Author: SvenVanCaekenberghe Time: 23 December 2015, 10:50:14.195912 pm UUID: b7ced20a-a7a4-4b0f-8f27-db73231eeecb Ancestors: STON-Core-SvenVanCaekenberghe.63 Added the ability to write and read Class and Metaclass instances using their global name === Name: STON-Tests-SvenVanCaekenberghe.59 Author: SvenVanCaekenberghe Time: 23 December 2015, 10:51:06.830762 pm UUID: 9f684bc1-45e1-4bfa-885b-c56ea178bfca Ancestors: STON-Tests-SvenVanCaekenberghe.58 Added unit test for the ability to write and read Class and Metaclass instances using their global name === Thanks to Norbert Hartl for requesting the feature and for test driving it.
